Driver Alert Control
The Driver Alert Control (DAC) function is designed to help alert the driver to erraticbehavior, e.g. if the driver is distracted orshowing signs of fatigue.
The objective of DAC is to detect slowly dete- riorating driving behavior and is primarilyintended to be used on major roads. The func-tion is not intended for use in city traffic. DAC is activated when the vehicle's speed exceeds 65 km/h (40 mph) and remainsactive as long as speeds are above 60 km/h(37 mph).
DAC detects the vehicle's position in the traffic lane.
A camera monitors the traffic lane's marker lines and compares the direction of the roadwith the driver's movements of the steeringwheel.
The vehicle is moving erratically in the lane.
If driving behavior becomes considerably erratic, thedriver will be alerted by thissymbol in the instrumentpanel, an audible signal and the message
Time for a
break.
If the vehicle is equipped with Sensus Navigation * and the Rest Stop Guidancefunction is activated, suggestions will also be provided for suitable places to take a break. The warning will be repeated after a short time if driving behavior does not improve.
WARNING
Driver Alert Control must not be used to extend a period of driving. The drivershould plan in breaks at regular intervalsand make sure they are well rested.
WARNING
An alarm from Driver Alert Control should be taken very seriously since a sleepy driveris often not aware of their own condition. If the alarm sounds or you feel fatigued:
Stop the vehicle safely as soon as pos- sible and rest.
Studies have shown that it is just as dan- gerous to drive while tired as it is to driveunder the influence of alcohol or otherstimulants.

Driver Alert Control limitations
Driver Alert Control (DAC) functionality may be reduced in certain situations.
In certain situations, the system may provide a warning even if it has not detected a change indriving behavior, e.g.: in strong crosswinds
on grooved road surfaces.
WARNING
In certain cases, driving behavior might not be affected despite the driver's fatigue – when using the Pilot Assist
* function –
resulting in the driver not getting a warning from DAC. It is therefore very important to always stop and take a break at the slightest signof fatigue, regardless of whether the func-tion has issued a warning or not.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

) is designed to
actively steer the vehicle on freeways, high- ways and other major roads to help the driverreduce the risk of the vehicle unintentionallyveering out of the lane.

Lane Keeping Aid is active at speeds between 65–200 km/h (40–125 mph) on roads withclearly visible traffic lane marker lines. On narrow roads, the function may be unavail- able and go into standby mode. The functionwill become available again when the roadbecomes sufficiently wide.
